Abstract

The invention discloses a method and a system for deduplicating files of a cloud storage system. The method comprises the following steps: reading a file to be uploaded, and calculating the information abstract value of the file; comparing the information abstract value of the file with the information abstract values of files which have existed in the cloud storage system, and if the file of which the information abstract value is the same as those of the files exists in the cloud storage system, stopping uploading the file. According to the method and the system for deduplicating the files of the cloud storage system disclosed by the invention, the information abstract value of the file is used, the information abstract value of the file is of uniqueness, and if the file of which the information abstract value is the same as those of the files exists in the cloud storage system to indicate that the data of the file has existed in the cloud storage system, the file is not uploaded any more, so that duplicate files are prevented from existing in the cloud storage system, and deduplication for the files of the cloud storage system is realized.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a method and system for deduplicating files in a cloud storage system. Background technique [0002] With the continuous development of Internet technology and the rise of cloud computing, network data is becoming more and more abundant, and cloud services are becoming more and more popular. In cloud service applications, ordinary users can upload their files to cloud servers by applying for a network disk account, and enterprises can use cloud service providers to build their own private cloud service platforms. An important function of cloud services is to provide cloud storage, which can store files in the cloud. Cloud storage can realize automatic data synchronization, historical version management, and files will never be lost. [0003] However, with the increasing number of users, the number of uploaded files is also increasing, but in fact there are a large number o...
